+Interceptors are a new feature, and require some project configuration.
+
+The exact shape of this has changed repeatedly, so this guidance is not complete yet.
+
+Things that might be involved, depending on what preview build SDK you're using:
+
+- `<Features>($Features);InterceptorsPreview</Features>`
+- `<InterceptorsPreviewNamespaces>$(InterceptorsPreviewNamespaces);Dapper.AOT<InterceptorsPreviewNamespaces>`
+
+This will be clarified for release.

+Dapper.AOT runs on interceptors, which requires at least C# 11. The language version is implied by
+your target .NET version, but can be changed manually - it is fine to use a different language
+version than the default for that target runtime, especially when going "higher". For example, you
+can use C# 12 on a project that targets .NET Framework (as long as you have up-to-date build tools).
+
+The easiest way to do this is via `<LangVersion>latest</LangVersion>`.
+
+For more information, see https://learn.microsoft.com/dotnet/csharp/language-reference/configure-language-version

+
+You're seeing this message because Dapper.AOT has found at least one place where it *could* help, and it
+isn't explicit whether you want it to do so.
+
+Dapper.AOT doesn't change any behaviours without your permission. You can *enable* (or disable) Dapper.AOT
+at any level by adding a `[DapperAot]` (or `[DapperAot(false)]`) attribute.
+
+To enable Dapper.AOT globally, add (usually to `AssemblyInfo.cs`, although it doesn't matter where):
+
+
+``` csharp
+[module: DapperAot]
+```
+
+Alternatively, if you only want it in a few places, use:
+
+``` csharp
+[module: DapperAot(false)]
+```
+
+and add `[DapperAot]` at more specific levels - types, individual methods, etc.
